Baseline the system with RTMT, record the number of registered phones and gateways<br>
2. Download phone firmware for CUCM 7.x<br>3. Copy firmware files to the remote gateways and configure TFTP for those files<br>4. Change option 150 to the remote gateways for each site one at a time and reset phones - phones download the new firmware<br>
5. Change option 150 to CM 4.x - phone register to CM 4.x again<br><br><b><span style="color: rgb(255, 0, 0);">Once the phones have downloaded the new firmware files for CUCM 7.x (7.1.2), will they still register to the CM 4.x server as normal - is this supported?</span></b><br>
<br><b>Upgrade tasks:</b><br>1. Backup the BARS<br>2. Install and run the Upgrade Utility all both PUB and SUB<br>3. Install and run the DMA on the PUB<br>4. Install CUCM 7.x<br>5. During the installation process of CUCM 7.x, provide the DMA file<br>
6. After installation, request license file from Cisco<br>7. Upload the license file.<br><br><b>Post-upgrade tasks:</b><br>1. Baseline the system with RTMT, complete registered phones and gateways<br>2. Monitor servers<br>
<br>Can someone comment to their experience of upgrading CM 4.x to CUCM 7.x?<br><br>Thanks<br> <br /><hr />Hotmail: Free, trusted and rich email service. <a href='http://clk.atdmt.com/GBL/go/171222984/direct/01/' target='_new'>Get it now.</a></body>
